AI Technical Summary
Technical Problem
During the processing of wooden components, external forces may cause the threaded rod to rotate, leading to the problem of loosening of the wood clamps.
Method used
The structure uses a bent plate with a rubber ring. The rubber ring makes full contact with the surface of the pressure block to fix the bent plate and the pressure block, preventing the threaded rod from loosening.
Benefits of technology
It effectively prevents the threaded rod from loosening under external force, and improves the clamping stability of the wooden components.

Abstract
This utility model provides a pre-fixing device for splicing wooden structures, belonging to the technical field of pre-fixing devices. The utility model includes a C-shaped frame, with a screw-hole block fixedly installed at one end of the C-shaped frame. A threaded rod is threadedly connected to the inner wall of the screw-hole block. An auxiliary rod is fixedly installed at one end of the threaded rod, and a pressure block is fixedly installed at the other end. A stop block is fixedly installed at one end of the C-shaped frame. This utility model uses a bending plate with a rubber ring to adjust the rubber ring, causing it to deform until its outer surface completely abuts against the outer surface of the pressure block. This allows the rubber ring to fix the bending plate and the pressure block, thereby providing auxiliary fixation between the pressure block and the C-shaped frame. This helps prevent the wooden components from being subjected to significant external force that could cause the threaded rod to rotate, leading to loosening of the clamping mechanism.
